Participant Flow

Induction Dosing Period (Weeks 0 up to 12), Maintenance Dosing Period (Weeks 12 up to 48), Minimum Post Treatment Follow-Up Period up to 12 weeks after last visit.

Participants were randomized to ixekizumab (ixe) 80 mg Q2W or Q4W during the Induction Dosing Period from Week 0 to Week 12. Participants received ixe Q4W in the Maintenance Dosing Period from Week 12 to Week 48, and then to the Post Follow up Treatment Period for at least 12 weeks.

Population: All randomized participants.

The Itch NRS is a patient-administered single-item 11-point horizontal scale anchored at 0 and 10, with 0 representing "no itch" and 10 representing "worst itch imaginable." Overall severity of a participant's itching from psoriasis (Ps) is indicated by circling the number that best describes the worst level of itching in the past 24 hours. Least Square Means (LS means) are from analysis of mixed-effects model for repeated measures (MMRM) and model includes treatment group, baseline value and timepoint.

The DLQI is a simple, patient-administered, 10-question, validated, quality-of-life questionnaire that covers 6 domains including symptoms and feelings, daily activities, leisure, work and school, personal relationships, and treatment. Response categories include "Not at all," "A little," "A lot," and "Very much," with corresponding scores of 0, 1, 2, and 3 respectively. Questions 3-10 also have an additional response category of "Not relevant" which is scored as "0". For all questions, if unanswered the question is scored as "0". Totals range from 0 to 30 (less to more impairment). LS means are from analysis of MMRM and model includes treatment group, baseline value and timepoint.

The BSA is the percentage involvement of psoriasis on each participant's body surface on a continuous scale from 0% (no involvement) to 100% (full involvement), in which 1% corresponds to the size of the participant's hand (including the palm, fingers, and thumb). The total BSA affected was the summation of individual regions affected. LS means are from analysis of MMRM and the model includes treatment group, baseline value, visit and treatment-by-visit interaction

Population: All randomized participants.

The PASI combines assessments of the extent of body-surface involvement in 4 anatomical regions (head, trunk, arms, and legs) and the severity of desquamation (scaling), erythema, and plaque induration/infiltration (thickness) in each region, yielding an overall score of 0 for no psoriasis to 72 for the most severe disease. Participants achieving PASI 75 were defined as having an improvement of at least 75% in PASI scores compared to baseline. LS means are from analysis of MMRM and the model includes treatment group, baseline value, visit and treatment-by-visit interaction.
